There is an opportunity to bulk free SKBs during reclaiming of resources after DMA transmit completes in ixgbe_clean_tx_irq. Thus, bulk freeing at this point does not introduce any added latency. Simply use napi_consume_skb() which were recently introduced. The napi_budget parameter is needed by napi_consume_skb() to detect if it is called from netpoll. Benchmarking IPv4-forwarding, on CPU i7-4790K @4.2GHz (no turbo boost) Single CPU/flow numbers: before: 1982144 pps -> after : 2064446 pps Improvement: +82302 pps, -20 nanosec, +4.1% (SLUB and GCC version 5.1.1 20150618 (Red Hat 5.1.1-4)) Joint work with Alexander Duyck.
